After such a pathetic experience with Clay Sim Cards, its worth it that everybody who wants a true review abt their services should read this review as well. I was hesitant to use Clay Sim Card for UK, but for my family’s convenience i took the same. When i landed in UK, inserted the sim card and hoped that the sim wuld start working but Nothing happened, tried everything, but nothing. The customer care did something and somehow i got some bare minimum signals but then the phone would work for a few mins in the day and would just not work for the rest. My idea of convenience had turned into a horrifying experience with zero response/ support from the customer team!! Such are services from Clay Telecom!!
